Viaduc de l'Anguienne, Bicycle bridge in Soyaux, France.

The Viaduc de l'Anguienne is a 400 m long, 12.2 m wide road viaduct on the eastern ring road of Angoulême, crossing the Anguienne valley at a height of 42 m. Designed by architect Charles Lavigne, it consists of two half-arches that cross at 15 m above the ground, with abutments 25 m apart at the base. The concrete arches support a flat deck, and in 2022 rigid safety fences were installed along the deck.

Designed by architect Charles Lavigne, who also designed the bridges to the Île de Ré and Normandy, the viaduct was studied in 1999 and 2000, tendered in March 1999, and built from October 2001 to 15 March 2004, opening to traffic in June 2004 at a cost of 12 million euros. In 2022 rigid fencing was installed along the deck.

The valley road beneath the viaduct was converted into a greenway, and an interpretation trail runs at the foot of the structure, explaining the landscaping work carried out there. A park with a water feature was laid out beside the Anguienne at the base of the bridge. The viaduct and valley can be seen from the ramparts of Angoulême.

The viaduct carries the D1000 eastern ring road of Angoulême, with one lane and a narrow hard shoulder in each direction; pedestrians and cyclists have no access to the deck. Walkers and riders instead use the greenway laid out on the valley road below, and an interpretation trail runs at the foot of the viaduct. The structure and the valley can be seen from the ramparts of Angoulême.
